本文整理了Java中com.esotericsoftware.kryo.io.Output.position()方法的一些代码示例，展示了Output.position()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Output.position()方法的具体详情如下：
包路径：com.esotericsoftware.kryo.io.Output
类名称：Output
方法名：position

Output.position介绍

[英]Returns the current position in the buffer. This is the number of bytes that have not been flushed.
[中]返回缓冲区中的当前位置。这是尚未刷新的字节数。

代码示例

代码示例来源：origin: apache/storm

/**
 * Serializes the given object into a {@link ByteBuffer} backed by the byte array returned by Kryo serialization.
 *
 * @param obj Object to be serialized.
 */
public ByteBuffer serializeToByteBuffer(Object obj) {
  output.clear();
  kryo.writeClassAndObject(output, obj);
  return ByteBuffer.wrap(output.getBuffer(), 0, output.position());
}

代码示例来源：origin: apache/flink

if (output.position() != 0) {
  throw new IllegalStateException("The Kryo Output still contains data from a previous " +
    "serialize call. It has to be flushed or cleared at the end of the serialize call.");
